WebmasterWorld Tests Banner Ads on Forums?

I just visited WebmasterWorld and I see for the first time ever, a banner ad, animated nonetheless, at the top of the page. The banner is promoting their PubCon in Vegas, and rotates images of sponsor logos. At this point the ad doesn't appear to link to anywhere, but that may change. No community reaction to it yet but I'll update this post as soon as we got some threads going (update, I started a thread linked to below).

This is major, I have never seen a banner of this size on WebmasterWorld before. Yes they have sponsors at the top right, but that is nothing like this.
